Abstract: 본 발명은 TiO 2 광촉매의 활용성 확대를 위한 저가형 광촉매 제조에 관한 것이다. 
     TiO 2 광촉매의 활성은 TiO 2 미분체의 입경이 작을수록 큰 것으로 나타났기 때문에 10∼20nm 이하의 미세한 분체가 제조되고 있다. 
     그러나, 이러한 미분체는 응집이 일어나기 쉬어 광촉매의 효율을 저하시키거나 용도를 제한하는 등의 문제를 야기시킨다. 
     따라서, 광촉매의 활용성을 고려하여 미립의 TiO 2 분말을 담체에 담지시켜 사용되고 있으며, 담체로서는 제올라이트 등과 같은 다공성 물질을 주로 사용하고 있다. 
     그러나, TiO 2 의 광촉매 반응은 빛(자외선)이 닿는 곳에서만 일어나므로, 다공성 산화물을 담체로 사용하는 것은 그다지 바람직하지 못하며, 또한 합성 제올라이트와 같은 다공성 물질은 가격이 비싸 광촉매의 가격을 상승시키는 요인이 되고 있다. 
     본 발명은 상기한 바와 같이 동작되는 종래 기술의 문제점을 개선하기 위하여 창안된 것으로서, 주 목적은 광촉매의 담체를 발전소 폐기물인 석탄회를 담체로 활용하고, 담체에 TiO 2 의 피복조건 및 열처리 조건을 정밀 제어하여 고활성이고 저가형인 TiO 2 광촉매의 제조 방법을 제공하는 것을 특징으로 한다.
